ABCUpload uses the Application Event Log to report important
information.

When the component is successfully registered or unregistered
it will report this via an information event.

If VBScript error logging is enabled (see Registry Settings)
these will be logged as warnings.

Serious errors or inconsistencies in the environment will be
logged as errors.

For example if the component is unable to create a temporary
file for caching uploads it will log an error "Unable to create
Binary Read Cache". This kind of error will affect server
performance but is not fatal.
